The Very Large Telescope (VLT) is a telescope operated by the European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT consists of four individual telescopes, each with a primary mirror 8.2 m across, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as Antu, Kueyen, Melipal and Yepun, which are all words for astronomical objects in the Mapuche language. The telescopes form an array which is complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture. (Wikipedia)
Have you ever wondered what’s it like to be inside these telescopes? DeepSkyVideos on YouTube gives us very informative video walkthroughs for all four telescopes: UT-4, UT-3, UT-1, and UT-2.
